Landmarks

Burnum Burnum Reserve lies between Bonnet Bay, Como, Jannali, Sutherland and Woronora. It extends for about two kilometres. The reserve effectively surrounds Bonnet Bay, with the only two roads leading into the suburb, cutting through it. Burnum Burnum Reserve hosts some plants that are almost extinct and are protected. However, it also represents a constant fire threat to Bonnet Bay, most notably manifesting in the 1994 Como bushfires. The reserve was originally known as "Jannali Reserve" but the name was changed in 2005 to commemorate Burnum Burnum, the prominent aboriginal Sutherland Shire resident. A small plaque details his famous speech in England at Australia's bicentenary in 1988.

A noteworthy feature of this suburb is that most of the streets are named after American Presidents. Washington Drive snakes its way through the length of the suburb.
